Compose: Compose a vector -

General Form:

compose name values value1 [ value2 ... ]      
compose name param = val [ param = val ... ]

The first form takes the values and creates a new vector, where the values may be arbitrary expressions.

The second form has the following possible parameters:

start	The value of name[0]
stop	The last value of name
step	The difference between successive elements of the created vector
lin	How many linearly spaced elements the new vector should have
log	The number of points, logarithmically spaced (not working)
dec	The number of points per decade, logarithmically spaced (not working)
center	Where to center the range of points (not working)
span	The size of the range of points (not working)
gauss	The nominal value for the used Gaussian distribution
sd	The standard deviation for the used Gaussian distribution
sigma	The sigma for the used Gaussian distribution
random	The nominal value for a uniform random distribution
rvar	The percentage variation for the uniform random distribution
